Create a regular expression term for soft hyphen to be able to search and replace (i.e. if set from another application which did a lousy job). Maybe an easy hack? The ICU supported Unicode literal syntax, e.g. \xAD \x{00AD} \u00AD \U000000AD \N{SOFT HYPHEN}\ as described in https://bugs.documentfoundation.org/show_bug.cgi?id=64495#c13 not works (any more?)
recent work around bug 152959, related?

OK - I made an error by using a hyphenated text which was hyphenated by LO - and these are no soft hyphens.
